NSA (National Sheep Association) urges caution amongst sheep farmers following the first bluetongue case in sheep.

In the wake of the confirmation by DEFRA on Thursday, December 7, regarding the first detected case of Bluetongue virus in sheep, the NSA issued a warning to sheep farmers residing within the Temporary Control Zone (TCZ) in Kent.

This confirmed case marks a total of nine animals identified with Bluetongue, specifically serotype 3 (BTV-3). All previously reported cases were found in cattle and are centralised around Kent. The most recent case was confirmed on the fifth farm premises following an epidemiological investigation conducted by the Animal and Plant Health Agency (APHA).

The UK's last outbreak of Bluetongue was back in 2007, since 2011 the virus had not re-emerged until November 11, 2023.

Expressing concern, NSA Chief Executive Phil Stocker commented: “It is disappointing, but not entirely surprising that BTV-3 has now been found in sheep. NSA understands the case was found in a mixed herd and identified through the routine surveillance testing currently being undertaken. BTV-3 is transmitted by biting midges which are most active between April and November. There has been no direct animal-to-animal spread of the disease in this current outbreak.”

Phil further emphasised: “NSA continues to urge any sheep farmers within the TCZ to of course comply with the movement restrictions in place, but also encourages those who might be traveling to the area or have stock heading off on winter keep to remain vigilant. The disease can spread rapidly amongst ruminants therefore swiftly notifying Defra is imperative for control.”

“Due to current restrictions within the TCZ NSA is asking that during this time Defra ease its concerns around the technicalities of linked holdings and CPH numbers, and instead encourage anyone with concerns of Bluetongue amongst their animals to come forward as soon as they feel the need.”

“As there is no vaccine available for BTV–3, farmers are encouraged to maintain exceptional levels of good biosecurity, including ensuring needles are changed between any routine vaccinations. Although current cases are in one county only, NSA encourages sheep farmers across the country to take a look at the official Defra guidance.”
